Abstract

With reference to Figure 1, and air sampler 1 for use in analysing biological or other analytes, comprises an airflow chamber 2 having an air inlet 3 and an air outlet 4. An extract from 5, draws ambient air in through the inlet 3, and then through the chamber 2, to discharge it back to atmosphere by way of an outlet 6. The airflow chamber 2 houses a cyclone air/liquid separator 7 through which the inflowing air is caused to pass. An injector 8 introduces liquid into air flowing through the air inlet 3. The cyclone separator 7 extracts this liquid and any entrained particles therein and discharges it from the airflow chamber 2, initially by way of a duct 9, where it is then conveyed to a collection vessel 12, by way of a three channel peristaltic pump 13, and a duct 14. The collection vessel 12 is housed within a Peltier-cooled holder 15 to maintain the contents of the vessel 12 within the 2 °C - 8 °C range which is desirable for maintaining the integrity of biological analytes such as bacteria or proteins. Analyses such as PCR, culture on agar plates or immunoassays may be performed on the collected samples. The holder 15 also houses sample bottles 16, 17, 18 and 19.
